Mine is in self supply mode and batteries are only charged by PV.Help: If I don't want it to ever charge the batteries from the grid, what should I put in a 48V megarevo? ( set up)

I tried to find the Amensolar manual, even using archive.org but was unable to find copy.has “ToU Enable" menu (Time Of Use) with 6 Time Slots very similar to the Amensolar N3H-X8.0-US 8kw which has a very good "Advanced Settings Menu" section in their manual with good explanations. (Latest Eg4 8k v1.4.0-1 manual is similar now. Except below)
Sorry for the delay.... Covid has me laid up again. I will have to see if I kept a downloaded copy somewhere (not on my phone)I tried to find the Amensolar manual, even using archive.org but was unable to find copy.
Are you able to share a copy with me ?
I am currently utterly frustrated to get my unit to work with ToU, see my attempt starting here:

Looking at the date stamps inside the ZIP file:
The only thing "new" is the firmware updating doc & the directory "tool setup"
There is already a newer version available of the 2nd file:
HybridInverter8KSNA_v1.4.13.B03D06.out <- D06 vs D02 above
I collect all information I can find about MEGAREVO (manuals/firmware etc) at my personal website (no ads/tracking) at
and with all the firmware together in
Curious to know if you resolved the issue, and what caused the problem?Tonight, for the first time ever since I have it, my MR started charging the battery from the grid!
But... but ... at the wrong time. It was still "medium rate" from my utility and I have no idea why it decided to start charging.
Also it did not discharge the battery to provide the load during "expensive" time-of-use.
I attached my current settings.
Could someone point out why/where the posible config is that points to start charging batteries from the grid at 19:35 (7:35PM) ?

No resolution yet.Curious to know if you resolved the issue, and what caused the problem?
Has anyone gotten this System Message? I've been trying to update my Megarevo for sometime now. But no luck so far.
The current firmware version is:
ARM: V1.03.06
DSP: V1.00.06

Interesting to see some issues with updates. I just saw that Will crashed his unit when trying to update. I think he assumed he has a brick now. Would like to know if these problems are related to one certain firmware version or what. I would assume Will's would have been from Sig. Solar.Same here I can't upload the .out file any solutions? The inverter completely crashed when updating the Firmware
Hi Alleydog77,It's not that I was having any specific issues. All of a sudden everything stopped working on one of my two inverters. Apparently an engineer from MegaRevo tried to do a firmware upgrade and it crashed. So I asked them for the files and I did it myself. That is how I came about having these files.
So I really can't tell you what has changed from one to the other.
check your clock setting, i bet its not running and frozen in TIME !!Curious to know if you resolved the issue, and what caused the problem?

I know you got a new printed circuit board which fixed your issue later.The seller is working on sending me a burner to upload the files. I will keep you guys posted.
No the printed board came already with the latest update, just plug and playI know you got a new printed circuit board which fixed your issue later.
But were you able to re-program the onboard CPU with that JTAG emulator ?
Did they send you a program and a file to program with ?
How to recover from a failed firmware update on Megarevo's R8KLNA
3. If the USB port doesn't work, try doing the firmware upgrade via RS-485, but you need to use a different file. When you run the Hybrid app with nothing connected and click upgrade, it will create a file ending in something like .bin_add_header.bin in the Hybrid/bin folder. That's the one you can use to upgrade via RS-485 (in the 485-Upgrade tab of course). This will take probably 8-13 minutes. You can do this with either the .out or .axf file.
Got one already, trying to be prepared for the worst4. If the .out upgrade still fails, then you may need to get your hands on a TI XDS110 programmer and create a special cable to flash the .out file directly to the control board. Use the UniFlash program to flash the .out firmware.
